Walden University Confidence Intervals and Afrobarometer Dataset Discussion Paper
In your Week 2 Assignment, you displayed data based on a categorical variable and continuous variable from a specific dataset. In Week 3, you used the same variables as in Week 2 to perform a descriptive analysis of the data. For this Assignment, you will calculate a confidence interval in SPSS for one of the variables from your Week 2 and Week 3 Assignments.
To prepare for this Assignment:
Review the Learning Resources related to probability, sampling distributions, and confidence intervals.
For additional support, review the Skill Builder: Confidence Intervals and the Skill Builder: Sampling Distributions, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you chose) from Week 2.
Choose an appropriate variable from Weeks 2 and 3 and calculate a confidence interval in SPSS.
Once you perform your confidence interval, review Chapter 5 and 11 of the Wagner text to understand how to copy and paste your output into your Word document.
For this Assignment:
Write a 2- to 3-paragraph analysis of your results and include a copy and paste of the appropriate visual display of the data into your document. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES.
Based on the results of your data in this confidence interval Assignment, provide a brief explanation of what the implications for social change might be.

Scenario Analysis, statistics homework help
Scenario:The owner of a small printing
company is considering the purchase of additional printing equipment to expand
her business. If the owner expands the business and sales are high, projected
profits (minus the cost of the equipment) should be $90,000; if sales are low,
projected profits should be $40,000. If the equipment is not purchased,
projected profits should be $70,000 if sales are high and $50,000 if sales are
low.
Are there options other than the purchase of additional
equipment that should be considered in making the decision to expand the
business?
If the owner is optimistic about the company’s future
sales, should the company expand by purchasing the equipment?
Is the owner’s optimism or pessimism about sales the
only factor that may impact the company’s profits?
The equipment to be purchased is known in the industry
to have a useful life of five years. How might this impact the printing
company?
